8 | If you are ready to start working on any of these TODO items, we |
9 | appreciate your help; please write to emacs-devel@gnu.org so we can be | |
10 | aware that the problem is being addressed, and talk with you how to do | |
7bea57c9 | 11 | it best. Since Emacs is an FSF-copyrighted package, please be |
2255d5b4 RS |
12 | prepared to sign legal papers to transfer the copyright on your work |
13 | to the FSF. | |

15 | * Simple tasks. These don't require much emacs knowledge, they are |
16 | suitable for anyone from beginners to experts. | |
17 | ||
bfb906ac DN |
18 | ** Convert modes that use view-mode to be derived from special-mode instead. |
19 | ||
9fe219e3 DN |
20 | ** Replace some uses of the preprocessor code in Makefile.in with the equivalent autoconf. |
21 | ||
c884b4d7 | 22 | ** Major modes should have a menu entry. Examples of modes that do |
bfb906ac | 23 | not have one at the moment and probably should: text-mode, inferior-lisp-mode. |
c884b4d7 | 24 | |
479be3f4 | 25 | ** Check if all items on the mode-line have a suitable tooltip for all modes. |
c884b4d7 | 26 | |
4e0ace23 DN |
27 | ** edebug and debugger-mode should have a toolbar. |
28 | It can use the same icons as gud. | |
29 | ||
c884b4d7 DN |
30 | ** Check what minor modes don't use define-minor-mode and convert them |
31 | to use it. | |
32 | ||
6d095958 GM |
33 | ** Convert all defvars with leading `*' in the doc-strings into defcustoms |
34 | of appropriate :type and :group. | |
35 | ||
63e51ddd GM |
36 | ** Remove any leading `*'s from defcustom doc-strings. |
37 | ||
38 | ** Remove unnecessary autoload cookies from defcustoms. | |
39 | This needs a bit of care, since often people have become used to | |
40 | expecting such variables to always be defined, eg when they modify | |
41 | things in their .emacs. | |
42 | ||
115f44b6 GM |
43 | ** See if other files can use generated-autoload-file (see eg ps-print). |
44 | ||
ba1c68de | 45 | * Small but important fixes needed in existing features: |
a9c1a157 | 46 | |
cc48343f RS |
47 | ** Flymake's customization mechanism needs to be both simpler (fewer |
48 | levels of indirection) and better documented, so it is easier to | |
49 | understand. I find it quite hard to figure out what compilation | |
50 | command it will use. | |
51 | ||
52 | I suggest totally rewriting that part of Flymake, using the simplest | |
53 | mechanism that sufficies for the specific needs. That will be easy | |
54 | for users to customize. | |
55 | ||
0989e765 SM |
56 | ** Compute the list of active keymaps *after* reading the first event. |
57 | ||
046ece71 KS |
58 | ** Distribute a bar cursor of width > 1 evenly between the two glyphs |
59 | on each side of the bar (what to do at the edges?). | |
60 | ||
d322eb9b RS |
61 | ** buffer-offer-save should be a permanent local. |
62 | ||
125fbe81 | 63 | ** revert-buffer should eliminate overlays and the mark. |
045744c6 MR |
64 | For related problems consult the thread starting with |

125fbe81 | 66 | |
f98abf6d RS |
67 | ** erase-buffer should perhaps disregard read-only properties of text. |
68 | ||
30c56b97 LT |
69 | ** Make occur correctly handle matches that span more than one line, |
70 | as well as overlapping matches. | |
71 | ||
d3a403e5 | 72 | ** Fix the kill/yank treatment of invisible text. At the moment, |
b9e6b498 | 73 | invisible text is placed in the kill-ring, so that the contents of |
2345130a SM |
74 | the ring may not correspond to the text as displayed to the user. |
75 | It ought to be possible to omit text which is invisible (due to a | |
b9e6b498 GM |
76 | text-property, overlay, or selective display) from the kill-ring. |
77 | ||
6f771c32 RS |
78 | ** Change the way define-minor-mode handles autoloading. |
79 | It should not generate :require. Or :require in defcustom | |
80 | should not be recorded in the user's custom-set-variables call. | |
81 | ||
af09dd78 RS |
82 | ** Feature to change cursor shape when Emacs is idle (for more than |
83 | a specified time). | |
84 | ||
4e07258f RS |
85 | ** The buttons at the top of a custom buffer should not omit |
86 | variables whose values are currently hidden. | |
87 | ||
ec0cf966 RS |
88 | ** Clean up the variables in browse-url. Perhaps use a shell command string to |
89 | specify the browser instead of the mushrooming set of functions. | |
90 | See also ESR's proposal for a BROWSER environment variable | |
91 | <URL:http://www.catb.org/~esr/BROWSER/browse-url.patch>. | |
92 | ||
528b6abc RS |
93 | ** Enhance scroll-bar to handle tall line (similar to line-move). |
94 | ||
95 | ** Make occur handle multi-line matches cleanly with context. | |
96 | ||
f98abf6d RS |
97 | ** In Custom buffers, put the option that turns a mode on or off first, |
98 | using a heuristic of some kind? | |
99 | ||
100 | ** Define recompute-arg and recompute-arg-if for fix_command to use. | |
101 | See rms message of 11 Dec 05. | |
102 | ||
7c14546c JD |
103 | ** Height returned by frame-parameter ... and height given to |
104 | make-frame does not mean the same thing. The former includes menu and | |
105 | tool bar lines, the latter don't. frame-parameter should return height | |
106 | without menu and tool bar lines. | |
107 | ||
f98abf6d RS |
108 | ** In Emacs Info, examples of using Customize should be clickable |
109 | and they should create Custom buffers. | |
110 | ||
321e4870 RS |
111 | ** The toolbar should show keyboard equivalents in its tooltips. |
112 | ||
74561a26 RS |
113 | ** Add function to redraw the tool bar. |
114 | ||
5a893bff RS |
115 | ** Redesign the load-history data structure so it can cope better |
116 | with evaluating definitions of the same function from different files, | |
117 | recording which file the latest definition came from. | |
046ece71 | 118 | |
4b4d11cc RS |
119 | ** make back_comment use syntax-ppss or equivalent. |
120 | ||
67ccd6cb GM |
121 | ** Consider improving src/sysdep.c's search for a fqdn. |
122 | http://lists.gnu.org/archive/html/emacs-devel/2007-04/msg00782.html | |
123 | ||
124 | ** Find a proper fix for rcirc multiline nick adding. | |

94172215 EZ |
127 | ** Implement `network-interface-list' and `network-interface-info' |
128 | on MS-Windows. Hint: the information is present in the Registry, | |
129 | under the keys | |
130 | HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Linkage\ | |
131 | and | |
132 | HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\<device>\ | |
133 | where <device> is the network device found under the first key. | |
134 | ||
4af1faa3 GM |
135 | ** Check for any included packages that define obsolete bug-reporting commands. |
136 | Change them to use report-emacs-bug. | |
137 | ||
7a00b900 NR |
138 | ** Allow fringe indicators to display a tooltip (provide a help-echo property?) |
139 | ||
d73803e6 CY |
140 | ** Add a defcustom that supplies a function to name numeric backup files, |
141 | like make-backup-file-name-function for non-numeric backup files. | |
142 | ||
b1a345ee MR |
143 | ** `dired-mode' should specify the semantics of `buffer-modified-p' for |
144 | dired buffers and DTRT WRT `auto-revert-mode'. | |
145 | ||
48abcfcc GM |
146 | ** Check uses of prin1 for error-handling. |
147 | http://lists.gnu.org/archive/html/emacs-devel/2008-08/msg00456.html | |
148 | ||
ba1c68de | 149 | * Important features: |
a9c1a157 | 150 | |
cc48343f RS |
151 | ** Having tabs above a window to switch buffers in it. |
152 | ||
153 | ** "Perspectives" are named persistent window configurations. We have | |
154 | had the window configuration mechanism in GNU Emacs since the | |
155 | beginning but we have never developed a good user interface to take | |
156 | advantage of them. Eclipse's user interface seems to be good. | |
157 | ||
158 | Perspectives work well even if you do the equivalent of C-x 4 C-f | |
159 | because of the distinction between view windows vs file windows. In | |
160 | Emacs this is more or less the "dedicated window" feature, but we have | |
161 | never really made it work for this. | |
162 | ||
163 | Perspectives also need to interact with the tabs. | |
164 | ||
165 | ** Imenu could be extended into a file-structure browsing mechanism | |
166 | using code like that of customize-groups. | |
167 | ||
168 | ** Display something in the margin on lines that have compilation | |
169 | errors. | |
170 | ||
171 | ** Compilation error navigation bar, parallel to the scroll bar, | |
172 | indicating where in the buffer there are compilation errors. | |
173 | Perhaps we could arrange to display these error indications on top | |
174 | of the scroll bar itself. That depends on to what extent toolkit | |
175 | scroll bars are extensible. | |
176 | ||
ba1c68de | 177 | ** Provide user-friendly ways to list all available font families, |
321e4870 RS |
178 | list fonts, display a font as a sample, etc. [fx is looking at |
179 | multilingual font selection for the Unicode branch of Emacs.] | |
5e101746 | 180 | |
3aa7c28e RS |
181 | ** Provide a convenient way to select a color with the mouse. |
182 | ||
09d04fb3 | 183 | ** Rewrite the face code to be simpler, clearer and faster. |
5e101746 | 184 | |
ba1c68de | 185 | ** Program Enriched mode to read and save in RTF. [Is there actually a |
c51b37fd | 186 | decent single definition of RTF? Maybe see info at |
1b2105d9 EZ |
187 | http://latex2rtf.sourceforge.net/.] This task seems to be addressed |
188 | by http://savannah.nongnu.org/projects/emacs-rtf/, which is still in | |
189 | very early stages. | |
6165b6e3 | 190 | |
ba1c68de | 191 | ** Implement primitive and higher-level functions to allow filling |
a9c1a157 RS |
192 | properly with variable-pitch faces. |
193 | ||
ba1c68de | 194 | ** Implement a smoother vertical scroll facility, one that allows |
d3a403e5 SM |
195 | C-v to scroll through a tall image. The primitive operations |
196 | posn-at-point and posn-at-x-y should now make it doable in elisp. | |
a9c1a157 | 197 | |
6ca1c497 | 198 | ** Implement intelligent search/replace, going beyond query-replace |
cbdf1202 | 199 | (see http://groups.csail.mit.edu/uid/projects/clustering/chi04.pdf). |
6ca1c497 | 200 | |
ba1c68de SM |
201 | ** Implement other text formatting properties. |
202 | *** Footnotes that can appear either in place or at the end of the page. | |
203 | *** text property that says "don't break line in middle of this". | |
6165b6e3 EZ |
204 | Don't break the line between two characters that have the |
205 | same value of this property. | |
ba1c68de | 206 | *** Discretionary hyphens that are not visible when they are at end of line. |
6165b6e3 | 207 | |
ec0cf966 RS |
208 | ** Internationalize Emacs's messages. |
209 | ||
4a7499a9 RS |
210 | ** Set up a facility to save backtraces when errors happen during |
211 | specified filters, specified timers, and specified hooks. | |
212 | ||
49322539 RS |
213 | ** Install mmc@maruska.dyndns.org's no-flicker change. |
214 | ||
07ff1e4b RS |
215 | ** Add a "current vertical pixel level" value that goes with point, |
216 | so that motion commands can also move through tall images. | |
217 | This value would be to point as window-vscroll is to window-start. | |
218 | ||
ec0cf966 RS |
219 | ** Address internationalization of symbols names essentially |
220 | as documentation, e.g. in command names and Custom. | |
a9c1a157 | 221 | |
ba1c68de | 222 | ** Make the Lucid menu widget display multilingual text. [This |
bf6394a6 DL |
223 | probably needs to be done from actual Emacs buffers, either directly |
224 | in the menu or by rendering in an unmapped window and copying the | |
f677a3a3 SM |
225 | pixels. The current code assumes a specific locale; that isn't good |
226 | enough even if X can render the arbitrary text] [The gtk | |
7bea57c9 DL |
227 | port now displays multilingual text in menus, but only insofar as |
228 | Emacs can encode it as utf-8 and gtk can display the result.] | |
f677a3a3 SM |
229 | Maybe making Lucid menus work like Gtk's (i.e. just force utf-8) is good |
230 | enough now that Emacs can encode most chars into utf-8. | |
a9c1a157 | 231 | |
ba1c68de | 232 | ** Remove the limitation that window and frame widths and heights can |
a9c1a157 RS |
233 | be only full columns/lines. |
234 | ||
ba1c68de SM |
235 | * Other features we would like: |
236 | ||
22f9eb9e CY |
237 | ** Make longlines-mode wrap lines based on screen position instead |
238 | of character position, so that variable-width fonts can be handled | |
239 | properly. | |
240 | ||
c3bb6fdb SM |
241 | ** Allow frames(terminals) created by emacsclient to inherit their environment |
242 | from the emacsclient process. | |
a37288ad SM |
243 | ** Remove the default toggling behavior of minor modes when called from elisp |
244 | rather than interactively. This a trivial one-liner in easy-mode.el. | |
0de301ed | 245 | |
a53e64cc SM |
246 | ** Create a category of errors called `user-error' for errors which are |
247 | typically due to pilot errors and should thus be in debug-ignored-errors. | |
248 | ||
39eadb4a RS |
249 | ** Give Tar mode all the features of Archive mode. |
250 | ||
9b8453da RS |
251 | ** Create a category of errors called `process-error' |
252 | for some or all errors associated with using subprocesses. | |
253 | ||
51f74c37 RS |
254 | ** Maybe reinterpret `parse-error' as a category of errors |
255 | and put some other errors under it. | |
256 | ||
1a500a73 | 257 | ** A function to tell you the argument pattern of functions. |
1b2105d9 | 258 | See `function-arity' in http://www.loveshack.ukfsn.org/emacs/fx-misc.el. |
1a500a73 RS |
259 | |
260 | ** Make byte-compile warn when a doc string is too wide. | |
261 | ||
9f4ba075 CY |
262 | ** Make byte-optimization warnings issue accurate line numbers. |
263 | ||
f95a20e7 RS |
264 | ** A function to check for customizable options that have been |
265 | set but not saved, and ask the user whether to save them. | |
266 | This could go in kill-emacs-query-functions, to remind people | |
267 | to save their changes. If the user says yes, show them | |
268 | in a Custom buffer using customize-customized. | |
269 | ||
8c9676fb DK |
270 | ** Record the sxhash of the default value for customized variables |
271 | and notify the user (maybe by adding a menu item or toolbar button, | |
272 | as the detection can occur during autoload time) when the default | |
273 | changes (meaning that new versions of the Lisp source with a changed | |
274 | default value got installed) and offer ediff on the respective | |
275 | customization buffers. | |
276 | ||
e0402468 | 277 | ** Emacs Lisp mode could put an overlay on the defun for every |
8c9676fb DK |
278 | function that has advice. The overlay could have `after-text' like |
279 | " [Function has advice]". It might look like (defun foo [Function | |
280 | has advice] (x y) The overlay could also be a button that you could | |
281 | use to view the advice. | |
e0402468 | 282 | |
17e55b2a RS |
283 | ** Add a function to get the insertion-type of the markers in an overlay. |
284 | ||
9c9c88db SM |
285 | ** ange-ftp |
286 | *** understand sftp | |
1b2105d9 EZ |
287 | This is hard to make work because sftp doesn't print status |
288 | messages. | |
289 | ||
9c9c88db SM |
290 | *** Use MLS for ange-ftp-insert-directory if a list of files is specified. |
291 | ||
ba1c68de SM |
292 | ** Ability to map a key, including all modified-combinations. |
293 | E.g map mouse-4 to wheel-up as well as M-mouse-4 -> M-wheel-up | |
294 | M-C-mouse-4 -> M-C-wheel-up, H-S-C-M-s-double-mouse-4 -> | |
295 | H-S-C-M-s-double-wheel-up, ... | |
a9c1a157 | 296 | |
ba1c68de SM |
297 | ** Beefed-up syntax-tables. |
298 | *** recognize multi-character syntactic entities like `begin' and `end'. | |
299 | *** nested string-delimiters (for Postscript's (foo(bar)baz) strings). | |
300 | *** support for infix operators (with precedence). | |
301 | *** support for the $ (paired delimiter) in parse-partial-sexp. | |
302 | *** support for hook-chars whose effect on the parsing-state is specified | |
303 | by elisp code. Thus a char could both close a string and open a comment | |
304 | at the same time and do it in a context-sensitive way. | |
305 | *** ability to add mode-specific data to the partial-parse-state. | |
306 | ||
2d1ef312 RS |
307 | ** Add a way to convert a keyboard macro to equivalent Lisp code. |
308 | ||
ba1c68de | 309 | ** Have a command suggestion help system that recognizes patterns |
a9c1a157 RS |
310 | of commands which could be replaced with a simpler common command. |
311 | It should not make more than one suggestion per 10 minutes. | |
6165b6e3 | 312 | |
ba1c68de | 313 | ** Add a way to define input methods by computing them (when first used) |
30a2aafd RS |
314 | from other input methods. Then redefine C-x 8 to use a |
315 | user-selected input method, with the default being the union of | |
316 | latin-1-prefix and latin-1-postfix. | |
317 | ||
a7abe867 | 318 | ** Switch the Windows port to using Unicode keyboard input (maybe). |
2fa4f835 EZ |
319 | Based on http://msdn2.microsoft.com/en-us/library/ms633586.aspx, |
320 | this boils down to (1) calling RegisterClassW function to register | |
321 | Emacs windows, and (2) modifying ALL system messages to use Unicode. | |
322 | In particular, WM_CHAR messages, which result from keyboard input, | |
a7abe867 | 323 | will then come in encoded in UTF-16. |
2fa4f835 EZ |
324 | |
325 | One advantage of switching to Unicode is to toss encoded-kbd usage, | |
326 | which will solve the problem with binding non-ASCII keys with | |
327 | modifiers. | |
328 | ||
a7abe867 RS |
329 | Problem: using this on Windows 9x/ME requires installing the |
330 | Microsoft Layer for Unicode (MSLU), which might not implement all | |
331 | the required functionality that is available built-in on Windows XP | |
332 | and later. We should not make this change if it would pressure | |
333 | users of unauthorized copies of older versions of Windows to | |
334 | downgrade to versions that require activation. | |
335 | ||
ba1c68de | 336 | ** Implement a clean way to use different major modes for |
06382b71 RS |
337 | different parts of a buffer. This could be useful in editing |
338 | Bison input files, for instance, or other kinds of text | |
1b2105d9 EZ |
339 | where one language is embedded in another language. See |
340 | http://www.loveshack.ukfsn.org/emacs/multi-mode.el and also | |
8b5e9361 | 341 | mmm-mode, as reference for approaches taken by others. |
a933dad1 | 342 | |
b76781cd RS |
343 | ** Arrange a way for an input method to return the first character |
344 | immediately, then replace it later. So that C-s a with | |
345 | input method latin-1-postfix would immediately search for an a. | |
a933dad1 | 346 | |
ba1c68de | 347 | ** Give start-process the ability to direct standard-error |
a933dad1 DL |
348 | output to a different filter. |
349 | ||
ba1c68de | 350 | ** Make desktop.el save the "frame configuration" of Emacs (in some |
a933dad1 DL |
351 | useful sense). |
352 | ||
ba1c68de | 353 | ** Give desktop.el a feature to switch between different named |
8ba148c7 RS |
354 | desktops. |
355 | ||
10bb671b RS |
356 | ** Add a cpio mode, more or less like tar mode. |
357 | ||
06382b71 RS |
358 | ** Save undo information in special temporary files, and reload it |
359 | when needed for undoing. This could extend undo capacity. | |
a933dad1 | 360 | |
ba1c68de | 361 | ** Change the Windows NT menu code |
a933dad1 DL |
362 | so that it handles the deep_p argument and avoids |
363 | regenerating the whole menu bar menu tree except | |
364 | when the user tries to use the menubar. | |
365 | ||
366 | This requires the RIT to forward the WM_INITMENU message to | |
367 | the main thread, and not return from that message until the main | |
0245b3ef | 368 | thread has processed the MENU_BAR_ACTIVATE_EVENT and regenerated |
a933dad1 | 369 | the whole menu bar. In the mean time, it should process other messages. |

ba1c68de | 371 | ** Get some major packages installed: W3 (development version needs |
93a759ba | 372 | significant work), PSGML, _possibly_ Cedet and ECB. |
590394eb GM |
373 | http://lists.gnu.org/archive/html/emacs-devel/2007-05/msg01493.html |
374 | Check the assignments file for other packages which might go in and | |
375 | have been missed. | |
376 | ||
7d6f3b3a GM |
377 | ** Possibly install python-mode in place of python.el, or combine the two. |
378 | Someone needs to do the work of figuring out who all the non-trivial | |
379 | python-mode.el contributors are and getting assignments. | |

384 | ||
ba1c68de | 385 | ** Make keymaps a first-class Lisp object (this means a rewrite of |
5dd31b13 SM |
386 | keymap.c). What should it do apart from being opaque ? |
387 | multiple inheritance ? faster where-is ? no more fix_submap_inheritance ? | |
388 | what else ? | |
e39fc314 | 389 | |
ba1c68de | 390 | ** Provide real menus on ttys. The MS-DOS implementation can serve as |
2fa4f835 | 391 | an example how to do part of this; see the XMenu* functions on msdos.c. |
e39fc314 | 392 | |
ba1c68de | 393 | ** Implement popular parts of the rest of the CL functions as compiler |
e39fc314 DL |
394 | macros in cl-macs. |
395 | ||
261b01c6 RS |
396 | ** Make compiler warnings about functions that might be undefined at run time |
397 | smarter, so that they know which files are required by the file being | |
398 | compiled and don't warn about functions defined in them. | |
399 | ||
ba1c68de | 400 | ** Highlight rectangles (`mouse-track-rectangle-p' in XEmacs). Already in CUA, |
a52ce7f8 | 401 | but it's a valuable feature worth making more general. |
e39fc314 | 402 | |
ba1c68de | 403 | ** Provide MIME support for Rmail using the Gnus MIME library. [Maybe |
bf6394a6 DL |
404 | not now feasible, given Gnus maintenance decisions. fx looked at |
405 | this and can say where some of the problems are.] | |
e39fc314 | 406 | |
ba1c68de | 407 | ** Eliminate the storm of warnings concerning char/unsigned char |
1b2105d9 EZ |
408 | mismatches that we get with GCC 4.x and proprietary compilers on |
409 | various systems. They make it difficult to spot the important | |
410 | warnings. | |
e39fc314 | 411 | |
ba1c68de | 412 | ** Fix anything necessary to use `long long' EMACS_INTs with GCC. |
eaf67bae | 413 | |
ba1c68de | 414 | ** Split out parts of lisp.h and generate Makefile dependencies |
eaf67bae DL |
415 | automatically. |
416 | ||
ba1c68de | 417 | ** Update the FAQ. |
eaf67bae | 418 | |
ba1c68de | 419 | ** Allow auto-compression-mode to use zlib calls if zlib is available. |
b04f7626 | 420 | [It's required for PNG, so may be linked anyhow.] |
1265b539 | 421 | |
ba1c68de | 422 | ** Add a --pristine startup flag which does -q --no-site-file plus |
1265b539 DL |
423 | ignoring X resources (Doze equivalents?) and most of the |
424 | environment. What should not be ignored needs consideration. | |
590394eb | 425 | [Do the existing -Q and -D cover this, or is more needed?] |
1265b539 | 426 | |
ba1c68de | 427 | ** Improve the GC (generational, incremental). (We may be able to use |
7bea57c9 DL |
428 | the Boehm collector.) [See the Boehm-GC branch in CVS for work on |
429 | this.] | |
19cc91fb | 430 | |
ba1c68de | 431 | ** Check what hooks would help Emacspeak -- see the defadvising in W3. |
e2849090 | 432 | |
a5bd14d3 RS |
433 | ** Add definitions for symbol properties, for documentation purposes. |
434 | ||
ba1c68de | 435 | ** Add horizontal scroll bars. |
00a18b59 | 436 | |
ba1c68de | 437 | ** Provide an optional feature which computes a scroll bar slider's |
e4ded23c | 438 | size and its position from lines instead of characters. |
c0460c17 | 439 | |
ba1c68de | 440 | ** Allow unknown image types to be rendered via an external program |
590394eb GM |
441 | converting them to, say, PBM (in the same way as PostScript?). [does |
442 | doc-view.el do this, or could it be extended to do this?] | |
d1c3f6b6 | 443 | |
ba1c68de | 444 | ** Allow displaying an X window from an external program in a buffer, |
d1c3f6b6 RS |
445 | e.g. to render graphics from Java applets. [gerd and/or wmperry |
446 | thought this was feasible.] | |
447 | ||
ba1c68de | 448 | ** Allow images (not just text) in the margin to be mouse-sensitive. |
d1c3f6b6 RS |
449 | (Requires recursing through display properties). Provide some way |
450 | to simulate mouse-clicks on marginal text without a mouse. | |
451 | ||
ba1c68de | 452 | ** Implement Lisp functions to determine properly whether a character |
d1c3f6b6 RS |
453 | is displayable (particularly needed in XFree 4, sigh). Use it to |
454 | define useful glyphs that may be displayed as images or unicodes | |
455 | (with ASCIIfied fallback via latin1-disp). Examples include | |
456 | box-drawing graphics in Custom buffers, W3 rules and tables, and | |
457 | tree displays generally, mode-line mail indicator. [See work done | |
8589dc17 | 458 | already for Emacs 23 and consult fx.] |
d1c3f6b6 | 459 | |
ba1c68de | 460 | ** Do something to make rms happy with fx's dynamic loading, and use it |
d1c3f6b6 RS |
461 | to implement things like auto-loaded buffer parsers and database |
462 | access in cases which need more than Lisp. | |
463 | ||
ba1c68de | 464 | ** Extend ps-print to deal with multiple font sizes, images, and extra |
d1c3f6b6 RS |
465 | encodings. |
466 | ||
ba1c68de | 467 | ** Provide portable undumping using mmap (per gerd design). |
d1c3f6b6 | 468 | |
48b194fd | 469 | ** Make byte-compile avoid binding an expanded defsubst's args |
8b5e9361 | 470 | when the body only calls primitives. |
48b194fd | 471 | |
ba1c68de | 472 | ** Use the XIE X extension, if available, for image display. |
e641b454 | 473 | |
ba1c68de | 474 | ** Make monochrome images display using the foreground and background |
51fe665a RS |
475 | colors of the applicable faces. |
476 | ||
ec68482b RS |
477 | ** Make `format-time-string' preserve text properties like `format'. |
478 | ||
fda12b27 RS |
479 | ** Optionally make the cursor a little thinner at the end of a line |
480 | or the end of the buffer. | |
481 | ||
ba1c68de | 482 | ** Port the conservative stack marking code of Emacs' garbage collector |
1b2105d9 EZ |
483 | to more systems, so that we can completely get rid of GCPROs. Note |
484 | that Boehm garbage collector provides this. | |
5e101746 | 485 | |
ba1c68de | 486 | ** Reorder defcustom's in each package so that the more important |
5005a9c0 EZ |
487 | options come first in the Customize buffers. This could be done by |
488 | either rearranging the file (since options are shown in the order | |
489 | they appear in the *.el files), or by adding a few :set-after | |
490 | attributes. | |
491 | ||
ba1c68de | 492 | ** Maybe document the features of libraries missing from the manual (or |
5e101746 RS |
493 | ancillary manuals, including the Lisp manual in some cases). |
494 | This is not worth doing for all of these packages and we need not | |
495 | aim for completeness, but some may be worth documenting. | |
496 | ||
497 | Here's a list which is probably not complete/correct: align, allout, | |
498 | artist, ansi-color, array, battery, calculator, cdl, cmuscheme, | |
657c5358 | 499 | completion, cua, delim-col, dirtrack, double, echistory, elide-head, |
5e101746 RS |
500 | easymenu, expand, flow-ctrl, format [format-alist], |
501 | generic/generic-x [various modes], kermit, log-edit, ledit | |
502 | [obsolete?], makesum, midnight [other than in Kill Buffer node], | |
503 | mouse-copy [?], mouse-drag, mouse-sel, net-utils, rcompile, | |
504 | snmp-mode [?], soundex [should be interactive?], strokes [start from | |
505 | the web page], talk, thingatpt [interactive functions?], type-break, | |
506 | vcursor, xscheme, zone-mode [?], mlconvert [?], iso-cvt, iso-swed, | |
507 | swedish, feedmail [?], uce, bruce, gametree, meese, page-ext, | |
508 | refbib, refer, scribe, sgml-mode, spell, texinfo, underline, | |
509 | cmacexp, hideif, mantemp [obsolete?], pcomplete, assoc, xml, | |
510 | cvs-status (should be described in PCL-CVS manual); other progmodes, | |
511 | probably in separate manual. | |
758830ba | 512 | |
ba1c68de | 513 | ** Convert the XPM bitmaps to PPM, replace the PBMs with them and scrap |
6772c8e1 GM |
514 | the XPMs so that the color versions work generally. (Requires care |
515 | with the color used for the transparent regions.) | |
bf6394a6 | 516 | |
ba1c68de | 517 | ** Convenient access to the `values' variable. It would be nice to have an |
758830ba JB |
518 | interface that would show you the printed reps of the elements of the |
519 | list in a menu, let you select one of the values, and put it into some | |
520 | other variable, without changing the value of `values'. | |
bf6394a6 | 521 | |
ba1c68de | 522 | ** (Controlled by a flag) make open and close syntax match exactly, |
c51b37fd DL |
523 | i.e. `(' doesn't match `]'. |
524 | ||
ba1c68de | 525 | ** Specify parameter ID-FORMAT in all calls to `file-attributes' and |
9ac8c83b LH |
526 | `directory-files-and-attributes' where attributes UID or GID are used. |
527 | Whenever possible, use value 'string. | |
528 | When done, change meaning of default value from 'integer to 'string. | |
529 | If value 'integer is used nowhere, remove the parameter ID-FORMAT from | |
530 | the definition of `file-attributes' and `directory-files-and-attributes' | |
531 | and from the calls. | |
532 | ||
cf4c9271 KH |
533 | ** Make language-info-alist customizable. Currently a user can customize |
534 | only the variable `current-language-environment'. | |
535 | ||
536 | ** Improve language environment handling so that Emacs can fit | |
537 | better to a users locale. Currently Emacs uses utf-8 language | |
538 | environment for all utf-8 locales, thus a user in ja_JP.UTF-8 locale | |
539 | are also put in utf-8 lang. env. In such a case, it is | |
540 | better to use Japanese lang. env. but prefer utf-8 coding system. | |
1f724d55 | 541 | |
321e4870 RS |
542 | ** Enhance locale handling: handle language, territory and charset |
543 | orthogonally and de-emphasize language environments. Use the locale | |
544 | to set up more things, such as fontsets, the default Ispell | |
545 | dictionary, diary format, calendar holidays and display, quoting | |
546 | characters and phrase boundaries, sentence endings, collation for | |
547 | sorting (at least for unicodes), HTTP Accept-language, patterns for | |
548 | directory listings and compilation messages, yes-or-no replies, | |
549 | common menu items when the toolkit supports it ... `locale-info' | |
550 | needs extending for LC_COLLATE &c. [fx started on this.] | |
551 | ||
1f724d55 KH |
552 | ** Eliminate the current restriction on header printing by ps-print. |
553 | Currently, a header can contain only single 1-byte charset in | |
554 | addition to ASCII. | |
555 | ||
556 | ** In ps-print, provide an user friendly interface to specify fonts. | |
557 | ||
1f724d55 KH |
558 | ** Enhance word boundary detection for such a script that doesn't use |
559 | space at word boundary (e.g. Thai). | |
560 | ||
cf4c9271 KH |
561 | ** Implement interface programs with major Japanese conversion server |
562 | in lib-src so that they can be used from the input method | |
563 | "japanese". Currently, most Japanese users are using external | |
564 | packages (e.g. tamago, anthy) or an input method via XIM. | |
1f724d55 | 565 | |
a53e64cc | 566 | ** Let LEIM handle the Mode_switch key like XIM does (i.e. a toggle like C-\ |
8b5e9361 | 567 | but which can also be used as a modifier). |
a53e64cc | 568 | |
d59e3c42 | 569 | ** Improve Help buffers: Change the face of previously visited links (like |
8b5e9361 GM |
570 | Info, but also with regard to namespace), and give the value of |
571 | lisp expressions, e.g auto-mode-alist, the right face. | |
d59e3c42 | 572 | |
5a473319 GM |
573 | ** Possibly make `list-holidays' eval items in the calendar-holidays variable. |
574 | See thread | |
575 | <http://lists.gnu.org/archive/html/emacs-devel/2006-02/msg01034.html>. | |
576 | [rgm@gnu.org will look at this after 22.1] | |
577 | ||
9e21382c GM |
578 | ** Possibly make cal-dst use the system timezone database directly. |
579 | See thread | |
580 | <http://lists.gnu.org/archive/html/emacs-pretest-bug/2006-11/msg00060.html> | |
581 | ||
590394eb GM |
582 | ** Possibly add a "close" button to the modeline. |
583 | The idea is to add an "X" of some kind, that when clicked deletes | |
584 | the window associated with that modeline. | |

ba1c68de SM |
587 | * Internal changes |
588 | ||
41a023e3 | 589 | ** Cleanup all the GC_ mark bit stuff -- there is no longer any distinction |
dcbccc4d CY |
590 | since the mark bit is no longer stored in the Lisp_Object itself. |
591 | ||
12cdb1c1 SM |
592 | ** Refine the `predicate' arg to read-file-name. |
593 | Currently, it mixes up the predicate to apply when doing completion and the | |
594 | one to use when terminating the selection. | |
595 | ||
1d919365 SM |
596 | ** Merge ibuffer.el and buff-menu.el. |
597 | More specifically do what's needed to make ibuffer.el the default, | |
598 | or just an extension of buff-menu.el. | |
599 | ||
600 | ** Use pcomplete by default in shell-mode. | |
601 | This means to make it behave (by default) more like the current code. | |
602 | Use it also for read-shell-command, M-x compile, ... | |
603 | ||
604 | ** Merge sendmail.el and messages.el. | |
605 | Probably not a complete merge, but at least arrange for messages.el to be | |
606 | a derived mode of sendmail.el. Or arrange for messages.el to be split | |
607 | into a small core and "the rest" so that we use less resources as long as | |
608 | we stick to the features provided in sendmail.el. | |
045744c6 | 609 | |
ba1c68de | 610 | ** Replace gmalloc.c with the modified Doug Lea code from the current |
1d919365 SM |
611 | GNU libc so that the special mmapping of buffers can be removed -- |
612 | that apparently loses under Solaris, at least. [fx has mostly done | |
613 | this.] | |
ba1c68de SM |
614 | |
615 | ** Rewrite make-docfile to be clean and maintainable. | |
616 | ||
617 | ** Add an inferior-comint-minor-mode to capture the common set of operations | |
618 | offered by major modes that offer an associated inferior | |
d3a403e5 SM |
619 | comint-derived mode. I.e. basically make cmuscheme.el/inf-lisp.el generic. |
620 | For use by sml-mode, python-mode, tex-mode, scheme-mode, lisp-mode, | |
621 | haskell-mode, tuareg-mode, ... | |
ba1c68de | 622 | |
8b5e9361 | 623 | ** Make SYNC_INPUT the default. [true since 2008-03-11] |
7cef6228 CY |
624 | All loops using immediate_quit need to be checked to ensure that |
625 | C-g can interrupt them, in case of an infinite loop. Once we | |
626 | switch to using SYNC_INPUT, we can remove the BLOCK_INPUTs in the | |
627 | allocation functions (allocate_string etc.) without worrying about | |
628 | data munging. | |
629 | ||
f57dad5a MB |
630 | ** Add "link" button class |
631 | Add a standard button-class named "link", and make all other link-like | |
632 | button classes inherit from it. Set the default face of the "link" button | |
633 | class to the standard "link" face. | |
634 | ||
2345130a SM |
635 | * Other known bugs: |
636 | ||
c3bb6fdb | 637 | ** `make-frame' forgets unhandled parameters, at least for X11 frames. |
48b8e4a0 | 638 | |
2345130a SM |
639 | ** a two-char comment-starter whose two chars are symbol constituents will |
640 | not be noticed if it appears within a word. | |
641 | ||
07ff1e4b RS |
642 | ** Fix unexelf.c to handle the .data.rel and .data.rel.local |
643 | sections made by GCC 3.4 on IRIX. | |
